The present invention relates to drives for motor vehicles and embodies, more specifically, an improved drive for a plural ty of wheels mounted upon a plurality of axles at one end of a motor vehicle.

The development of multi-wheel' drives has heretofore utilized the conventional type c of axle which extends transversely across t frame and is an unsprung element In adwhic ated above,

dition to increasing the unsprun weight of the vehicle, such constructions decrease the clearance between the road surface and the frame, re uiring the frame to be elevated considerab and the center of ravit thereof correspondingly raised. here centl been provided a form of drive 1n the driving axles are individually mounted upon the lame and the drive transmitted thereto independently'of the cooperating driving wheelsin so far as theunsprung portion of the drive is concerned."

It is with the last mentioned type of drive that the present invention. is concerned and it is contemplated herein to afiord a design which incorporates a plurality of individually mounted wheels in a construction which is provided with an'improved mechanism for transmitting the drives to such independently mounted wheels.

An object of the invention, therefore, is to provide an' improved mechanism for transmitting the drive from the propeller shaft to a plurality of individually mounted wheels. Y

A further object of the invention is to provide a drive of the above character in which the weight of the unsprung elements for transmitting the drive is considerably reduced and the center of gravity of the frame lowered.

A further object of the invention is to provide a drive for a plurality of wheels mounted in the above manner, such drive increasing the clearance between the road surface and the frame elements. I

Further objects, not specifically enumer- Wlll be apparent as the invention is-described in greater detail in connection with the accompan ing, drawings, wherein: Figure 1 is a p an view, partly broken a. The spiders b I chor tubes 0.

a drive cona' is carried for transmitting the drive from e present inan internal combustion engine to the driving wheels.

Driving wheels 6 are mounted upon spiders I) which are journaled upon anchor tubes 0, carried in brackets a? on the under portion of the .longitudinalframe members are provided with stub shafts 6 upon which the wheels are mounted and ofl'set arms 6 are provided with extensw'ns b which are journaled upon the an- Nuts 0 may be provided for preventing the extensions 6 from slipping off of the anchor tubes, and torsional springs of engage the spiders to mount the frame yieldlngly thereon and support its weight in the desired position.

Differential housings d are journaled on the anchortubes and are provided with differential mechanisms d having driving ring ears d between which power is divided. hafts' b are carried within the spiders b and formed with bevel gears b", one of which gears engages the corresponding driving gear d on the differential mechanism (1, and the other of such gears engaging a ring gear 6 I rear driving wheels are mounted upon the forward anchor tube in a manner similar to that in which the rear driving wheels are mounted. Two similar arrangements are thus provided to support and drive each pair of wheels and it will be seen that the resulting construction affords greater clearance for the vehicle than heretofore available, at the same time effectively transmitting the drive of the respective individually mounted driving wheels. These Wheels are'mounted to accommodate all irregularities in the road surface and are independently yieldable without impairing the drive transmitted thereto.

lVhile the invention has been shown as embodied in the specific construction illustrated in the accompanying drawings, that the elementsthereof may be changed in form, design and arrangement of parts without departing from the scope of the present invention as defined in the appended claim.

What I claim is:

A drive for motor vehicles comprising a frame, a drive shaft thereon, a plurality of pairs of driving wheels, spaced anchor tubes on the frame, a differential carried by each tube, a third difi'erential driven by the drive shaft and driving the first differentials, spiders journaled on the tubesat either sides of the difl'erentials, means to mount the wheels on the spiders, and angular drive shafts'carried by the spiders for transmitting the drive from the differentials to the wheels.
